What does 100W on a tire represent?

[VanTyler]

100 is the load index of the tire, corresponding to a maximum load capacity of 800 kilograms per tire; W represents the speed rating of the tire, with W indicating a maximum speed of 270 kilometers per hour. Here are detailed explanations about tires: 1. Definition: A tire is a circular elastic rubber product mounted on various vehicles or machinery, typically installed on metal rims. It supports the vehicle body, absorbs external shocks, ensures contact with the road surface, and guarantees the vehicle's driving performance. 2. Function: Tires are often used under complex and demanding conditions. During operation, they endure various deformations, loads, forces, and extreme temperature effects. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning ability. Additionally, they are required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, highlighting the significant demand for rubber in tire manufacturing.
